OK thanks I think there is something wrong with the inverter as it will go into run mode and boost mode but not buck mode. I have ordered another inverter so will try again when I get this one. I bought the first one in a unknown condition and I have not been able to get the 12v dc to dc side ...

Just tried charging again with revision 5 software in buck mode and nothing happened at all. It did not even say it had gone into buck mode. Switched back into boost mode and started charging again and got 17amps roughly going into battery measured with a clamp meter on the positive cable fed by a ...

Thanks for your reply so now does this mean that you never use in boost mode . Also which revision software did you introduce this.

Just watched Johu's video again and it looked like the charger settings says he had it buck mode not boost. My question his is this right or an optical illusion as all the previous posts say it as to be in boost mode

What voltage is the battery

Forgot to ask but voltage is your high voltage battery

Good work zookeeper what voltage did you put into mg1 as I could not go above 190vac

I had a voltmeter on the positive and negative posts of the battery . Before charging process began it read 25v and while charging it read 36v . So next step is to keep playing with the settings to get a 27v reading when charging the lead acid batteries and check the ampage . The charging process is ...

Just a quick update got charging up and running today. I found out if I put more than 190vac into MG1 it tripped the gen3 relays out. I also could only get my 24v battery to charge at 36v if I changed settings started to trip the relays.

Thanks again what about the burning smell and we're would you put the heater inseries with what.

Thanks for the response Johu. My setup 24v battery to gen3 relay box to main dc power supply inlet on inverter. Put into boost mode with forward and reverse connected to 12v. CPWM + 470ohm resistor to 12v and CSDN pin29 to 12v. No power connected to MG1. Next I thought I would try and disconnect ...

Seeking verification want to charge 24v battery to 27v Max using 240ac (320vdc)
1 chargemode boost
2 chargecur 5 (5amps is 13amps Max from a 13amp 240ac supply)
3 chargekp 0 (is this value used)

Sorry to hear that.

Thanks for the reply Retrozero if it's the start and stop inverter that's all I wanted to know as I could not read what it said on the phone. Please post how you get on. I'm going to download to the lastest firmware tomorrow.

Thanks for the reply just watched Johu's video again and he activates charge mode on a separate tablet which is connected to the board by Wi-Fi. The charge mode function is in the commands list the problem I'm having I never get this option in my command list so I can't activate it thanks again Paul.

Got my inverter into boost mode no ac connected. Verified this by looking in spot values and it says boost instead of run. Go back to commands and still no pi command to start charge mode will somebody please explain why I don't have this option in the commands thanks Paul

Any updates?

Thanks Johu I thought so but I can't find it in the foc how do I get to it please help

This might sound stupid but understand everything apart from the pi charge controller. Is it hardware or software? In Johu video it looks like it is just software which he turns on using the touch screen. If so where can I get it and how does it work and connect to the inverter any help much ...

My gen2 inverter settings running a toyota mgr. I have looked for Damiens settings for the gen2 from the tuning video which he said he was going to post but cannot find them as I was going to post there.

Thanks for the reply look forward to hearing your progress on charging and maybe YouTube video of it.

Thanks for that should the pinswap be set to 5 for the gen2 inverter running a mgr as in the tuning video by damien and Joho.

Hi again got everything wired up and getting a message in spot values saying udcbelowudcsw wondered what it means and would it stop the motor spinning. I'm trying to run the motor on 12v hv and what should the pinswap say in the latest foc. Any help would be welcome thanks Paul

Hi again got my board connected to power and ground got 2 red led one flashing. Put in the Wi-Fi module and red led on. Green led flashes when I change firmware. So my question is does the board need to be wired to a inverter to show parameters as all I see is like spinning wheels at the side thanks ...

Yes it is this board and thanks for your help
